During the ubuntu set up I have to skip the connect to the internet part because there's an "internal error" every time I try to connect. After skipping it, everything is fine until I need to restart at the end. When it boots back up I get an error saying it has to start in low graphics mode. I've read other people's solutions to this problem but none have worked for me. I have a 1GB AMD Radeon(TM) HD 7670M card and a AMD Quad-Core A8-4500M.
